Self-cleaning rotary valve is designed for dosed supply of materials with surface humidity more than 1.5%, bulk density not more than 1.8 g/cm3, temperature from −50 °С to +250 °С.

Reliable dosing of materials by means of rotary valves is provided in case of continuous feeding the material from hopper into the loading branch pipe and absence of the product adhesion to the valve rotor cells walls.

Rotary valves are designed in the following climatic versions: UKhL3, UKhL4, T3 according to GOST 15150-69 for economic needs and export. Valves are available for operation in macroclimatic areas with moderate and tropical climate both in indoor and outdoor areas protected from atmospheric precipitation.

Self-cleaning rotary valve is designed to avoid suction among various technologic line sections when material with increased humidity of 1.5–15% passes through the valve.

Rotary valve performs the following tasks:

  • self-cleaning rotary valve doses the material, it possesses the additional function of self-cleaning. It is possible to regulate the material feed by means of varying the rotor speed;
  • valve of ZShS-45 type represents housing with loading and unloading branch pipes and two side covers. Rotor with horizontal shaft is located inside. Rotor is of cylindrical form. It consists of two disks and blades between them. Blades form the individual cells. Shaft ends bear the bearings mounted into covers from the both sides. Dedicated labyrinth-and-cup seals are provided for shaft sealing in the places of output from covers, sealing air supply is provided to avoid the pulverized coal entry into sealants;
  • gear motor equipped with frequency converter allows the drive adjustment from 10% to 150% of its rated speed and smooth start performance.
